So I have a Peavey Studio Pro 112. When I turn it on the speaker just plays REALLY low volume with crackling sounds and I have to turn it up to nearly max volume and play a chord for it to pop and then it starts working fine. I know that this isn't because of my guitar though...any ideas?

loose wire? Bad connection?

I can think of a dozen things that could be doing that, everything from a loose speaker connection to faulty power transistors. What you've said tells us bugger all, sorry.

What would you suggest as the first thing to check out on it to fix it though?

I'd start by cleaning all the jacks and check the speaker connection. The next place I would look would be the power supply filter caps, then the power transistors. I'd also be looking for dry joints on the board. Then I'd be testing coupling capacitors.
Basically, it could turn into a huge job just trying to identify the fault.

^ Cath is saying in a nice way it will cost more to diagnose and fix than the amp is worth

It very well could be something simple. Start poking around but wear gloves and mind your capacitors. Speaker wire and input jacks are safe and simple without opening up the amp.
